Oh, and Why do I never show them in the act of the actual kiss?

Because the anticipation gives us that little bit more shiver up the spine than actually seeing it happen. It's why it's hotter, when dancing with a partner, to not quite touch. Why visual jokes are funnier when we don't see the whole thing and have to fill in the answer ourselves. I could go on and on, but anyway, if you never show the actual kiss, it's fine with me. :-)
